SEMITRANSPARENT ELECTROPHORETIC INFORMATION DISPLAYS (EPID) EMPLOYING MESH-LIKE ELECTRODES

摘要

An electrophoretic display includes a plurality of intersecting grid and cathode lines which are spaced one from the other by means of an insulating material. The grid and cathode lines are associated with an anode electrode which constitutes a planar glass plate having deposited thereon a thin layer of ITO or a similar metal. Interposed between the cathode and grid structure and the anode plate is a mesh electrode which is relatively of the same size as the anode plate. Control voltages are applied to the mesh structure and the anode electrode to further control particle propagation. The conventional anode structure may be entirely replaced with the mesh-like structure to provide an electrophoretic display which can be optimumly illuminated by back lighting.
